If you go clipless (ie, special shoe/pedal interface) seriously look into Speedplay. They have a bunch of models and are about the only set up that can handle extreme leg positioning issues. The road pedals can get pricy, so stick with the cromo axles and you will be fine. I set my son up with Specialized shoes, arch supports and extra wedging inside. The shoes come with a built in 11/2 degree of valgus wedge and we added another degree with the Specialized footbeds and wedges. I am not a big Specialized fan, but their shoes and footbeds seem to be very well researched, thus I use them. These pedals/shoes will not be walking around touring shoes so that may bugger the deal for you.

Pedal extenders or simple spacers may be in order as well. Talk to a fitter at the LBS.
